NAILING DIE.

Application led March 26, 1923. Serial No. 627,766.k

To all whom t may concern.' n

Be it known that I, JOSEPH H. Perma citizen of the United States, residing at South Hamilton, inthe county of Essex and l State of Massachusetts, have invented certain Improvements in Nailing Dies, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several igures.

This invention relates to nailing dies and has for its object the improvement of such dies `with a view to increasing their usefulness by making a single die capable of operating upon a wide Variety of work.v `In the accomplishment of the above stated object the invention providesk a nail-v ing die constructed and arranged to accommodate itself to work having different characteristics such, fo-r example, as the requirement that nails be driven at certain locations, which may be somewhat dierent in different individual pieces of work, in combination with features which facilitate quick changing of the die to accommodate substantial chan esy in the work such, for example, as in c anging from the nailing of one size shoe to another.

One useful application of the invention is in a nailing Y`die for heeling machinesj intended to `be used in attaching rubber heels by nails driven from the outside of theshoe, and the illustrative embodiment of the invention which is hereinafter described in detail is such a heeling machine die. Itishould be understood, however, that `the invention is adaptable ,to other operations than lattaching rubber heels and that the specific construction herein disclosedI is shown for illustrative purposes only. I

My copending application, Serial N o. 612,254, tiled Jan. 12, 1923, discloses a rnech-y anism which has been used successfully for rubber heel attaching and which has proved to be greatly superior tothe nailing dies heretofore used for that purpose. The present invention may, in a certain sense, be regarded as an improvement uponand de;-l velopment of the invention disclosed in the said application. n

In my prior invention 1 avplurality of freely movable nail guiding tubes wereem `ployed, inconnection with a seriesof interchangeable pattern y plates i 'wh ich provided for adjustment of the tubes to different naili ing patterns. A corresponding series of ring-like heel holderswere also provided and these were .interchangedI to accommo-y date work of different sizes, at the same time that the nailing pattern plates were. inter changed. By.l the present invention` the necessity for interchanging elements ofsucha mechanism when changing, for example, from onesize heel to another, is; eliminated, and a self-contained mechanismy isprovided which requires only a single, si1nple manipulative adjustment v to accommodate it to any of the various requirements of an ordi-l nary run of work. v

More specifically a construction is .pro-y vided whereby, manipulation Yof a fsingle. knob changes both the pattern of the nails ing and. the size of the work holder, to snit the work at hand. f

Further features andfadvaritages of the v invention will be. understood and apprecia-ted from reading the following detailed description `of one satisfactory, practical embodiment thereof in `connection with the accompanying drawings, in which fFig.` 1 is aL plan view `of a heelingr ma'- chine nailing die embodying theffinvention; Fig.y 2 is a front elevation of the die; f Fig.- 3. is 'a Avertical section on the. line 3-.-3 of Fig. 1; andl Figa is a perspective view'showingthe parts disassembled but in. their proper super-posed relation.4 Y Referring now to the drawings, `10 .indi- Cates a die block having projecting ytongues 12- at` itsl sides and so constructed that it may lbe readily inserted in the guides provided for that purpose in a well known type ofl 'commercial heeling machine such,for eX- ample, as that' disclosed in my prior Patent No. 1,431,980, dated October 17, 1922, towhich reference maybe had for amorey complete disclosure of the heeling machine vThe die block 10 is chambered to provide openings 14: extending entirely through it.

When, however, a change is being made from one class of work to another as, for example, when a different number of nails are to be used the die, being self-contained, may be easily'and quickly exchanged for another which is suitable for the new lkind of work to be operated upon.

Having described the invention, what is claimed as new and desired to be secured by Letters Patent is v l. A nailing die having a plurality of nail guiding tubes supported to permit free pivotal movement oi their nozzle ends, and controlling means arranged to engage said nozzle ends and variably control the pattern of the nailing.

EZ. In a nailing die the combination of a plurality oi nail guiding tubes supported to permit free pivotal movement about points remote from their nozzle ends, and manipulative means constructed and arranged to eifect said pivotal movement of the tubes simultaneously.

3. lin a nailing die, the combination of a plurality of nail guides, a work gage, and a controller constructed and arranged to change simultaneously the relative positions of the guides and the relative positions of the guides and the gage.

il. In a nailing die, the combination of a gage, and a cam device constructed and ar- `rainged to change the spacing between the guides and to adjust the gage relatively to the guides.

5. A nailiig die comprising a selflocating nail and driver guide having a nozzle shaped to co-operate with the formation of the work at a predetermined point, and yielding means for normally maintaining the nozzle in a predetermined position but permitting it to move sufciently to accom modate itself to the Work. v

6. A nailing die comprising a nail and driver guide mounted to permit transverse movement between limits, and spring means tending to maintain the guide approximately midway between said limits.

7. A nailing die comprising a nai-l and driver guide mounted for pivotal movement about a point remote from its nozzle end, rigid locating means surrounding said nozzle end and spaced therefrom suilciently to allow a limited amount of movement thereof, and a spring surrounding the guide and engaging the locating means, said spring tending to center the nozzle end of the guide in the space. y

In testimony whereof I have signed my name to Ithis specifica-tion.
